- Create a folder called customTags in the /www/ folder.
In this Hands On we are going to create an encapsulated cfc that holds error data.
Functions Used: ArrayAppend, ArrayLen
- Create a new file called errorBean in the /www/admin/cfc/ folder.
In this hands on example, you are going to add the list and create functionality in the Admin for the blog posts and categories.

There are many attributes that the cfhttp tag can take. The simplest cfhttp call can be done like this:
In this hands on example, you are going to make a call to Twitter to get a list of your latest tweets and output them to the contact page.

We say "more difficult" because no web application can be 100% secure.
There are several shifts in thought required.
